Device for the prevention of collisions of birds with transparent barriers

Abstract

A passive method for protecting flying birds against the danger of colliding into transparent barriers is disclosed. The method involves placing on the transparent barrier an image of the center portion of the web of an orb web building spider especially including in the image an adornment on the web known as the stabilimentum. The stabilimentum is known to be an advertisement by the spider for the purpose of deterring birds from flying into the web, an event which both animals wish to avoid. When the spider web image is placed on the transparent barrier, flying birds will take evasive action and thus avoid harmful collisions. Since the spider web image is mostly transparent, it does not block out a large portion of the transparent barrier.

I claim: 
     
       1. A passive method of deterring birds from flying toward a window barrier comprising; providing means for deterring birds from a window barrier comprising a substrate having an image of a spider stabilimentum pattern, and   attaching said substrate on said window barrier.   
     
     
       2. The method of claim 1 wherein said image further comprises a pattern of a center portion of a spider web. 
     
     
       3. The method of claim 2 wherein said image further comprises a figure of a spider. 
     
     
       4. The method of claim 1 wherein said substrate is a decal having adhesive means on one surface for facilitating said step of attaching said substrate to said window barrier. 
     
     
       5. A device for deterring birds from colliding with a transparent window barrier, said device comprising; a means for deterring birds from a transparent window barrier, said means for deterring birds comprising a substrate bearing the image of a spider stabilimentum and a center portion of a spider web, and said substrate having adhesive means on one surface thereof, wherein said substrate is adhesively attached to said transparent window barrier.   
     
     
       6. The device of claim 5 wherein said image further comprises the image of a spider. 
     
     
       7. The device of claim 5 wherein said substrate is a decal having a transparent portion and said image. 
     
     
       8. A device for deterring birds from colliding with a barrier, said device comprising; a means for deterring birds from said barrier, said means for deterring comprising a decal adhesively attachable to said barrier, and said decal having a transparent portion and an image of a spider stabilimentum.   
     
     
       9. The device of claim 8 wherein said decal further comprises the image of a spider web. 
     
     
       10. The device of claim 8 wherein the decal further comprises the image of a spider.
